[PATCH 00/25] Change time_t and clock_t to 64 bit

This patchset change default time_t and clock_t to 64 bit in
include/uapi/asm-generic/posix_types.h. The existing 32 bit architectures override
these define to 32 bit in arch posix_types.h.

There is request to support 64 bit time_t for new architecture [1]. According to the
previous discussion we had (in [2]), defining suseconds_t as 64-bit, while probably
reasonable for LP64 or LP64+ILP32 architectures, but can makes things troublesome
for ILP32 architectures, not to mention the additional overhead.

This series is compiled tested on ARM, mips, powerpc32 and x86_64, but only boot
tested on ARM.

These patches are also available on this branch:
